jonathan, i have a list, a horrible list, of the deadliest u.s. school shootings. columbine, of course, killed 12 students before the two shooters took their own lives. we're hearing reports now that up to 20 children may have been shot. it is hopefully -- we say this every single time we cover one of these things, a line in the sand. there has got to be a measurable xhank, some kind of reaction. one would hope that there will be some political capital to report in the way we handle gun and gun violence in this country. >> what's so traumatizing, beyond the trauma that we're already experiencing is the fact that we're talking about the possibility of multiple children dead. not high school students. want college students. not pedestrians on the street. grown adults. we're talking about children who went to school today, you know, starry-eyed, going to school with all the hope and joy that comes with that. especially in this holiday season and to now learn that a gunman went into that school. someone from the outside. i mean, just we don't know who this gunman is. w
